Have 1333 MHz CL7 RAM, Speccy says 657MHz, 9-9-9-24?

Hey guys, I got a set of 2 x 2GB G.Skill Ripjaws RAM running at 1333 MHz with a CAS Latency of 7

I'm on Speccy and it says it's at 657MHz and the timing says 9-9-9-24

Is this normal? I though motherboards wouldn't have problems reading the default clocks for the speeds it natively supports?

I have a Gigabyte GA-P55-USB3

  1. 1) Your memory is running at DDR3 1333. DDR is Double Data Rate, so software monitoring programs show it at half the speed. You just need to double it can it comes out to pretty much 1333.

    2) Timings typically have to be adjusted to their state CAS Latency, unless utilizing XMP. Motherboards default to CAS Latency 9. I would just adjust your timings to what is stated on the sticks and just make sure your voltage is at the rated voltage, as well.
  2. Sooo... what do I do to properly adjust the timing... in the BIOs, what do I do...
  3. Look at page 42 & 43 of the manual ( http://download.gigabyte.us/FileList/Manual/mb_manual_ga-p55-usb3_v2.0_e.pdf ).

    Set the following timings controls to match what is on your RAM sticks:
    CAS Latency Time
    tRCD
    tRP
    tRAS
    Command Rate(CMD)

    Example: 7-7-7-24-2T
